Question about Sonos Roam

Can I use the Roam to stream a Bluetooth sound medium from my mobile phone to the Roam and then play it on the entire Multiroom? The background is that I often come home from work and want to finish watching the current video. At home, the mobile phone just sounds shabby, especially when various Sonos speakers are standing around in the same room and do nothing. I don't care if the Roam plays the sound or not, as long as the other speakers (One/Arc ect) are running. Thanks for the feedback. Sonos is really annoying
